You run a regression analysis on a bivariate set of data (n = 80). With a = 78.4 and y = 56.8, you obtain the regression equation y = 3.267x - 199.333 with a correlation coefficient of r = 0.121. You want to predict what value (on average) for the response variable will be obtained from a value of x = 50 as the explanatory variable. What is the predicted response value? y = -35.9 X (Report answer accurate to one decimal place.) Check Answer

Question

The answer is NOT -35.9! 

You run a regression analysis on a bivariate set of data (n=80n=80). With ¯x=78.4and ¯y=56.8, you obtain the regression equation y=3.267x−199.333with a correlation coefficient of r=0.121.You want to predict what value (on average) for the response variable will be obtained from a value of x=50as the explanatory variable.

What is the predicted response value?
y = Incorrect Not -35.9!!!
